What is Nanotechnology?
Nanotechnology is the science, engineering, and application of materials and devices at the nanoscale, typically between 1 and 100 nanometers. A nanometer is one-billionth of a meter, and at this scale, materials exhibit unique physical, chemical, and biological properties that are distinct from their bulk counterparts. These unique properties enable innovations across various fields, including medicine, electronics, and materials science.
How does Nanotechnology work?
Nanotechnology works by manipulating matter at the molecular and atomic levels. This involves the design and creation of
nanomaterials and
nanodevices with precise control over their structure. Techniques such as
self-assembly,
lithography, and
chemical vapor deposition are commonly used in the fabrication process. These methods allow scientists to build structures atom by atom or molecule by molecule, resulting in materials with enhanced properties like increased strength, lighter weight, and higher reactivity.
